-
-SYNOPSIS
-
- void elf_symtab_read (bfd *abfd, CORE_ADDR addr,
- struct objfile *objfile)
-
-DESCRIPTION
-
- Given an open bfd, a base address to relocate symbols to, and a
- flag that specifies whether or not this bfd is for an executable
- or not (may be shared library for example), add all the global
- function and data symbols to the minimal symbol table.
-
- In stabs-in-ELF, as implemented by Sun, there are some local symbols
- defined in the ELF symbol table, which can be used to locate
- the beginnings of sections from each ".o" file that was linked to
- form the executable objfile. We gather any such info and record it
- in data structures hung off the objfile's private data.
